выбрать один столбец из ИСКЛЮЧЕНИЯ результата

Question

Я просто хочу ItemID из результата этого оператора EXCEPT:

SELECT     ManufacturerID, ItemID, ItemName, Description, Notes, Dimensions, BasePrice, SpecialPrice, OrderMinimumQuantity, OrderMultipleQuantity, 
                      OnHandQuantity, Category, IntroDate, BackOrderDate, UPC, PriceLevel1, PriceLevel2, PriceLevel3, PriceLevel4, PriceLevel5, PriceLevel6, PriceLevel7, PriceLevel8, 
                      PriceLevel9, PieceBox, Cubes, UnitOfMeasure, UDF1, UDF2, UDF3, UDF4, UDF5, AdditionalImageCount, PhotoName, AppendProductModifiers, Discontinued, 
                      IsDeleted
FROM         StagingProducts
WHERE     (ManufacturerID = 10)
EXCEPT 
SELECT     ManufacturerID, ItemID, ItemName, Description, Notes, Dimensions, BasePrice, SpecialPrice, OrderMinimumQuantity, OrderMultipleQuantity, 
                      OnHandQuantity, Category, IntroDate, BackOrderDate, UPC, PriceLevel1, PriceLevel2, PriceLevel3, PriceLevel4, PriceLevel5, PriceLevel6, PriceLevel7, PriceLevel8, 
                      PriceLevel9, PieceBox, Cubes, UnitOfMeasure, UDF1, UDF2, UDF3, UDF4, UDF5, AdditionalImageCount, PhotoName, AppendProductModifiers, Discontinued, 
                      IsDeleted
FROM         Products
WHERE     (ManufacturerID = 10)

Что было бы действительно хорошо, если бы я мог сохранить результаты оператора EXCEPT для использования в запросе INSERT INTO ниже по строке.

По сути, я собираюсь удалить записи, основанные на возврате ItemID из этого оператора EXCEPT из таблицы Products, а затем вставить новые записи, которые являются результатом того же оператора EXCEPT, - со старым входом и новым.

ОБНОВЛЕНИЕ - рабочий раствор:

Answer 1

Поскольку вы работаете в SQL Server 2008, возможно, вы захотите узнать MERGE о ваших потребностях в синхронизации, но чтобы ответить на заданный вопрос, вы можете сделать

DECLARE @T TABLE (ItemID INT PRIMARY KEY)

;WITH T As
(
Your Big Statement
)
INSERT INTO  @T
SELECT ItemID 
FROM T

Answer 2

Забудьте CTE и табличную переменную: просто используйте MERGE.

CTE просто делает то, что WHEN [NOT] MATCH часть MERGE все равно делает.

У вас уже естьпромежуточная таблица (StagingProducts), поэтому вам не нужно @T.

MERGE будет выглядеть примерно так (я сократил список столбцов с помощью ...):

MERGE INTO Products
USING StagingProducts
   ON Products.ManufacturerID = StagingProducts.ManufacturerID
      AND Products.ItemID = StagingProducts.ItemID
      AND Products.ManufacturerID = @ManufacturerID
WHEN MATCHED THEN
   UPDATE 
      SET ItemName = StagingProducts.ItemName, 
          Description = StagingProducts.Description, 
          Notes = StagingProducts.Notes, 
          ...
          IsDeleted = StagingProducts.IsDeleted 
WHEN NOT MATCHED THEN
   INSERT (ManufacturerID, ItemID, ItemName, Description, Notes, ..., IsDeleted)
      VALUES (ManufacturerID, ItemID, ItemName, Description, Notes, ..., IsDeleted);

Answer 3

Отдельно от ответа Мартина об использовании MERGE ...

Вы можете использовать NOT EXISTS, который дает тот же план запроса и более читабелен.

SELECT     ManufacturerID, ItemID, ItemName, Description, Notes, Dimensions, BasePrice, SpecialPrice, OrderMinimumQuantity, OrderMultipleQuantity, 
                      OnHandQuantity, Category, IntroDate, BackOrderDate, UPC, PriceLevel1, PriceLevel2, PriceLevel3, PriceLevel4, PriceLevel5, PriceLevel6, PriceLevel7, PriceLevel8, 
                      PriceLevel9, PieceBox, Cubes, UnitOfMeasure, UDF1, UDF2, UDF3, UDF4, UDF5, AdditionalImageCount, PhotoName, AppendProductModifiers, Discontinued, 
                      IsDeleted
FROM         StagingProducts SG
WHERE
     (ManufacturerID = @ManufacturerID)

NOT EXISTS (SELECT * FROM
         Products P
       WHERE
          P.Key1 = SG.Key1 AND SG.Key2 = SG.Key2 AND SG.Key3 = SG.Key3)
